Part Number: TSW14J56EVM
I wanted to evaluate the ADS52J65EVM which required the TSW14J56EVM. I had purchased these boards June 27, 2019 and was just finally
getting around to using them. One minor issue and one major issue arose. First, the available download of the High Speed Data Converter Pro Software
was version 5.0. When running with this eval board and the ADS52J65 driver software, it warned that some GUI functions may not be compatible and to
use version 4.5 to 4.9. But I can't find how to get version 4.9 of the High Speed Data Converter Pro software. However this seems minor.
The main problem is the TSW14J56EVM is failing the DDR test. With separate 5V supplies to both boards, and turning on the TSW14J56EVM, it then pulls
about 1.5 Amps. I then start up the High Speed Data Converter software, which recognizes the TSW14J56EVM serial number to select,
and sometime after here I get the compatibility message about the GUI version which I ignore. I then download
the ADS52J65 firmware (from the upper left). This causes more initialization of the TSW14J56EVM FPGA. In this process LED D8 briefly flickered ON, but is
ultimately off and LED's D7 and D6 are on. I saw in some user forum that this alone is a sign of memory failure. LED
D3 is ON. In attempting the first exercise of the ADS52J65 (80 MSPS, 4 lane, ADC - not ramp), and 32767 samples,
when I hit capture, D3 turns OFF, and D4 blinks ON/OFF. Then after a timeout I get the error message for Read DDR to file.
Unless there some common board error, or the GUI compatibility, unless the user forums are incorrect, it means the board is unusable. What do I do
with it? It costs almost $1200-1300 at the time purchased directly from TI. Is there any warranty option? I can buy one from Digit-Key for almost $1500, for
quick turn-around to minimize further delays, but this is a lot of money to throw around for a university group waiting for new grant funding in a pandemic!
